摘　　要：综述了变形镁合金的基本塑性变形特征,变形镁合金常温下因塑性较差限制其发展,故改善变形镁合金的塑性成为变形镁合金研究与应用中急需解决的重点。细化晶粒、提高变形温度和超塑性变形等方法可以显著提高变形镁合金的塑性,本文介绍了以上2种方法改善变形镁合金塑性的最新研究进展。Technologies of plastic deformation for wrought magnesium alloys are reviewed in this paper. Magnesium alloys have relatively low plasticity at room temperature,which prevents development of magnesium alloys. So ductility enhancement becomes a key to the research of wrought magnesium alloys. Grain refinement,raising the deformation temperature and super-plasticity can improve ductility of wrought magnesium alloys remarkably,which are promising methods. The recent progress of ductility enhancement of wrought magnesium alloys is reviewed from above two aspects.
